Architectural Floor Plans & Structural Wall FAQ
Statutory guidance on floor plan interpretation, BCA renovation permits, and cryptographic provenance.
Why are floor plans on commercial portals watermarked, and why is PropAce 100% unwatermarked?
Commercial advertising portals (such as PropertyGuru and 99.co) apply large diagonal defensive watermarks across floor plan diagrams to prevent third-party scraping. PropAce bypasses commercial portal scraping entirely by harvesting directly from statutory public sector sources (official HDB BTO master sales brochures hosted on assets.hdb.gov.sg) and developer CAD blueprints. These architectural layouts are served 100% vector-clean, high-resolution, and unwatermarked for homeowners, buyers, and interior architects.
How do I identify non-hackable structural RC walls versus hackable partitions on a floor plan?
In Singapore architectural plans, structural walls are represented as thick, solid black or hatched lines. These indicate Reinforced Concrete (RC) columns, shear walls, and structural shear cores that support the building's structural integrity; under BCA (Building and Construction Authority) and HDB renovation guidelines, these walls are strictly non-hackable. In contrast, thin solid lines or double hollow lines represent non-structural drywall, lightweight concrete blocks, or hollow clay bricks, which can be legally demolished or altered with an approved renovation permit.
How is the cryptographic SHA-256 provenance of each floor plan verified?
Every floor plan indexed in PropAce's Single Source of Truth (SSOT) database is paired with the SHA-256 cryptographic hash of its original master source document (e.g., the statutory HDB sales PDF or developer launch dossier). By calculating the sha256sum of the source document, any homebuyer, architect, or valuer can independently verify that the layout, square meterage, and architectural boundaries have not been altered, tampered with, or hallucinated.
Can I download and use these floor plans for interior design, space planning, and contractor quotes?
Yes. All floor plans hosted on PropAce can be inspected in full-screen CAD lightbox mode, zoomed to inspect wall junctions, and downloaded directly in high-resolution WebP format. You can forward these blueprints directly to your interior designer (ID) or contractor to obtain precise space planning and carpentry quotations.
What is the difference between GFA, Strata Area, and internal usable area on Singapore floor plans?
Gross Floor Area (GFA) measures the total covered floor space under URA planning guidelines. Strata Area (which appears on your legal Title Deed and OTP) includes the internal living area, air-conditioner ledges, balconies, private enclosed spaces (PES), and roof terraces. The internal usable area excludes AC ledges and non-strata communal spaces. PropAce explicitly itemizes whether a layout includes a balcony, private enclosed space, utility room, or AC condenser ledge to ensure complete transparency.
